Embodiment 1

[0037] Step A: Degreasing the pre-selected Chinese toon seeds to remove fat-soluble components. Specifically, the above-mentioned Chinese toon seeds can be degreased by 95% ethanol or petroleum ether.

[0038] Preferably, before the degreasing treatment of the Chinese toon seeds in step A, the Chinese toon seeds can be pulverized, so that the Chinese toon seeds have a higher degreasing rate.

[0039] Step B: extract the degreased Chinese toon seeds by adding water to reflux, and perform suction filtration and decompression treatment to obtain a concentrated solution. In this step, the solid-liquid ratio of adding water and reflux extraction is 1:13g / ml, the extraction time is 119min, and the number of extractions is 3 times.

[0040] Step C: Deproteinizing the concentrated solution to obtain a deproteinized solution. The present invention preferably adopts the sevage method to deproteinize.

[0041] Step D: adding ethanol to the deproteinized solution, and controlling the e...

Abstract

The present invention is applicable to the technical field of natural product extraction technology, and provides a method for extracting polysaccharides from Toona sinensis, comprising the following steps: A: degreasing the seeds of Toona sinensis to remove fat-soluble components; And perform suction filtration and decompression treatment to obtain a concentrated solution; C: deproteinize the concentrated solution to obtain a deproteinized solution; D: add ethanol to the deproteinized solution, and control the content of ethanol to 70% to 90% %; E: The mixed solution composed of the ethanol and the deproteinized solution is left to stand for a predetermined time in an environment of 1°C to 5°C; F: The above mixed solution that has been left to stand is suction-filtered, and then dehydrated with absolute ethanol Drying is carried out after washing to obtain the polysaccharide of Toona sinensis. The method of the invention can efficiently extract the polysaccharides in the Chinese toon seeds, and the polysaccharides have functions such as immune regulation, anti-inflammation, and anti-oxidation, and the toxicity is relatively low.

Description

technical field [0001] The invention relates to the technical field of natural product extraction technology, in particular to a method for extracting polysaccharides from Toona sinensis. Background technique [0002] Toona sinensis is the fruit of the genus Toona sinensis in the Meliaceae family. Toon, first recorded in "Tang Materia Medica" [1] , widely distributed in my country, is a well-known homologous plant of medicine and food, and its root bark, bark, buds, leaves, and fruits can be used as medicine. Toona sinensis is a traditional Chinese medicinal material in my country. It has the effects of expelling wind, dispelling cold, and relieving pain. disease [1-2] . [0003] At present, studies have found that Toona sinensis contains active ingredients such as phenols, tannins, alkaloids, saponins, steroids, terpenes, volatile oils and oils. [3-6] . Polysaccharides have special effects such as immune regulation, anti-oxidation, lowering blood sugar and blood lipids...
